Thank you NZXT for sending me the Sentry II fan controller. Fan controllers have always held a little soft spot in my book. I started modding my computer more years ago than I can remember. Back before you could even find a case with a window or in any color other than beige I don’t think you could even buy windows at first. One thing I always wanted to do was build a fan controller. At that time I only remember Sunbeam as the only company that put out a mass produced fan controller, otherwise you built your own. It was not too difficult, the plans and parts were out there for all, it just required a solder gun, drilling and some other light tools. You gained total control of your fans though. Fast forward a decade (or more) to the NZXT Sentry II, all you need is a screwdriver, tape (provided) and wire management skills (or not). Not only do you get total control of your fans, you get touch screen technology, alarms, digital temperature displays and auto control. All this for less money that it cost me to build my own back then.
